Transition in the Finnish forest-based sector: Company perspectives on the bioeconomy, circular economy and sustainability
2019
The forest-based sector is affected by many profound structural changes and the increasing complexity of the business environment due to, for example, the mature markets of many core products and the aims for bio and circular economies and more sustainable societies. In response to the changing business environment, forest-based sector firms need to restructure their business models and develop new products and services. From the Finnish perspective, new forest-based businesses are crucial in the transition to successful and sustainable bio and circular economies. Views on the concepts of bioeconomy, circular economy and sustainability vary according to which parties are involved. Developin…
Structural and Dynamical Complexities of Risk and Catastrophe Systems: an Approach by System Dynamics Modelling
2009
Risk and catastrophe are complex systems. Within the scope of this paper, we focus our attention on structural and dynamic complexities of catastrophes and on the possibility of modelling and simulating its double complexity with a formal and methodological framework: the General Systems Theory and System Dynamics modelling. Then we briefly propose a model of urban catastrophe related to a flood. After we propose some ways of research allowing exceeding the limits related to the modelling.
International survey of violence risk assessment practices
2016
International audience; Objective Mental health professionals are routinely called upon to assess the violence risk presented by their patients, frequently aided by structured instruments. Though surveys of risk assessment and management have been conducted, these efforts have been largely circumscribed to individual countries and have not compared the practices of members of different professional disciplines. Method A web-based survey was developed to examine the international use of structured instruments in the violence risk assessment process across five continents and to compare the perceived utility of such instruments by psychologists, psychiatrists, and nurses. The survey was trans…
Techno-economic analysis of integrated processes for the treatment and valorisation of neutral coal mine effluents
2020
Abstract The disposal of highly-concentrated neutral coal mine effluents into the environment constitutes a severe threat to the natural ecosystem. This work proposes and compares five novel treatment chains to purify the effluent and recover raw materials. The chains present different combinations of pre-treatment and concentration technologies. In all cases, the solution sent to the concentration step is concentrated up to saturation to recover water and sodium chloride. Concerning the technical performances, the treatment chains are compared in terms of total energy demand and salt recovery. Furthermore, the economic feasibility assessment is performed via a novel global parameter, i.e. …
Towards the implementation of circular economy in the water softening industry: A technical, economic and environmental analysis
2020
Abstract To reduce the environmental impact of the industrial sectors, circular strategies should be implemented to purify the effluents and recover raw materials. In this context, a novel integrated methodological approach is proposed to identify the most suitable strategy to improve the sustainability of the water softening industry via the treatment and recycling of the produced wastewater. Different concentration technologies and energy supply systems are compared to find economically feasible and environmentally friendly treatment systems. The investigated chains present the same pre-treatment step (nanofiltration and crystallization) and different concentration technologies: Multi-Eff…
Design of a novel membrane-integrated waste acid recovery process from pickling solution
2019
Abstract Hydrochloric acid pickling is a common practice in steel manufacturing industry. During the process, acid is consumed to dissolve surface oxides and metals ions are accumulated in the solution, which becomes less effective with time. In addition, the costly and risky waste acid disposal is another issue affecting the hot-dip galvanizing industry. In this work, a novel sustainable waste acid recovery process from pickling solutions based on circular approach is proposed to tackle these issues. The innovative system allows (i) the continuous regeneration of pickling solutions to enhance process rate and performance and (ii) minimise the highly expensive and environmentally risky wast…
A plant-wide wastewater treatment plant model for carbon and energy footprint: Model application and scenario analysis
2019
Abstract A new model for accounting carbon and energy footprint of wastewater treatment plants (WWTPs) is proposed. The model quantifies direct and indirect greenhouse gas (GHG) emissions related to biological and physical processes of a WWTP. The model takes into account several innovative aspects with respect to already available literature models: i. kinetic/mass-balances; ii. nitrification as a two-step process; iii. nitrous oxide (N2O) formation during nitrification and denitrification both in dissolved and off-gas forms. A full-scale application has been performed by adopting the case study of a real WWTP. A scenario analysis was performed to quantify the influence of: composition of …
Taxonomy of homicides of women in intimate partner relationships
2018
Intimate partner violence prevention is a challenge that has received wide international interest. Homicide is the most serious result of this type of violence, although its prevalence is low and its etiology is complex. This paper briefly reviews the description of the problem from a gender perspective and the existence of asymmetry, the perspective of violence and its description of differential risk factors, and the ecological model that connects personal, contextual, and societal variables, presenting a more integrative proposal. Studies analyzing and comparing homicide profiles are described, as well as the state of the art regarding risk assessment, with special attention to the impli…
Factores dinámicos en el comportamiento de delincuentes juveniles con perfil de ajuste social. Un estudio de reincidencia
2017
RESUMEN Este estudio tiene por objeto evaluar el riesgo de reincidencia, analizando el impacto de los factores dinámicos en adolescentes en conflicto con la ley (ACL). Para ello, se evalúa una muestra de 157 ACL con perfil de ajuste social mediante el instrumento para la evaluación del riesgo de violencia de adolescentes Structured Assesment of Violence Risk in Youth (SAVRY), además de otras técnicas de análisis cualitativo que triangulan el proceso empírico. Por un lado, destaca que la amplia estructura relacional y la vinculación intermitente con redes formales e informales de aprendizaje y empleo de que disponen los ACL con perfil de ajuste estiman un buen nivel de ajuste futuro y una ba…
